SPECIFICATION forming part of Letters Patent No. 508,728, dated November14, 1893. f

Application tiled March 13,1893. Serial No. 465,726. (No model.)

To all whom it may concern:

Be it known that we, WALTER LEWIS and AUeUsTUsH. Ross, citizens ot theUnited States, and residents `of Philadelphia, Pennsylvania,haveinvented certain Improvements in Ash-Sifters, of which the following isa specification.

One object of our inventionA is to so construct an ash sifter as toprevent the escape of dust during the sifting operation as well asduring the time that the coarse ashes, coal and clinkers are beingdumped from the sitter, a further object being to provide convenientmeans for dumping such coarse ashes, dac., from the sifter and fordirecting them into a suitably located receptacle. These objects weattain in the manner hereinafter set forth, reference being had to theaccompanying drawings, in Which- Figure 1, is a perspective view of ourimproved ash sifter, showing the parts in the position which they assumewhile the ashes are being sifted. Fig. 2, is aperspective View showingthe parts in position for dumping the ashes, &c. Fig. 3, is a transversesection of the device with the parts in the position shown in Fig. l;and Fig. 4, is a transverse section with the parts in the position shownin Fig. 2.

A represents part of an ordinary barrel, box, or other receptacle forthe ne ashes, and B a lid or cover fitting snugly thereto so as toprevent the escape of dust around it. In this lid or cover Bis a centralrectangular opening to which is fitted, with reasonable snugness,asenii-cylindrical hood comprising two quarter segments D D', the endplates of each of these segments being hung to the lid or cover B bymeans of pins a so that said segments can be raised above the lid orcover B, as shown in Figs. 1 and 3, or can be dropped so as to meetbelow said lid or cover, as shown in Figs. 2 and 4. The casing ofone-half of the hood is so constructed, by preference, as

to slightly overlap the other half when the hood 4is lifted, as shown inFigs. l and 3, the two parts of the hood being then secured together byany suitable form of catch or fastening.

The rotary sieve F has projecting shafts or spindles b extending beyondthe heads of the same and adapted to bearings in arms f which are hungto blocks g secured to the lid or cover B, so that said rotary sieve maybe ad j usted to the position shown in Figs. l and 3,where it can beinclosed by the hood D D', the ends of the hood having recesses for thereception of the shafts or spindles of the sieve when said hood israised, so that while the sieve is being rotated and the ashes are beingsifted, the hood incloses the sieve and prevents the escape of dust andfine ashes, the latter dropping directly into the barrel or receptaclebeneath the sieve. When the ashes have been fully sitted the two partsof the hood are permitted to swing downward, as shown in Figs. 2 and 4,so as to close, from below, the opening in the lid or cover B, and thusagain prevent the escape of dust or fine ashes from the barrel. The armsfare now free to be lifted so as to swing the rotary sieve to theposition shown in Figs. 2 and 4, the discharge of the coarse ashes, coaland cinders from the sieve being effected by opening a doort' formingpart of the sieve casing. This door has formed upon its inner sideinclined wings or guides fm which direct the ashes, &c.,.to a centralpoint and thus insure their delivery into a bucket, pail, or otherreceptacle suitably located.

When the sieve is in use the door t' is held in place by any availableform of catch or fastening.

Having thus described our invention, we

claim and desire to secure by Letters Patent- 1. The combination of arotary sieve, with the lid or cover having an opening within which is atwo-part hood pivoted to said lid or cover so that its two parts can beswung upward to meet above the sieve, or downward to meet below thesame, substantially as specified.

2. The combination of the lid or cover, the rotary sieve, the pivotedarms carrying the same, and a two-part hood pivoted to the lid or covers-o that its two parts can be swung upward to meet above the sieve whenthe latter is in use, or downward vto meet below the sieve when thelatter has to be swung outward for discharging its contents,substantially as specified.

3. The combination of the lid or cover, the arms hung thereto, and thesieve having shafts or spindles carried by said arms, and a hinged coverwith inclined guide Wings thereon, substantially as specified.

In testimony whereof .we have signed our names to this specification inthe presence of lo two subscribing witnesses.
